Actually, it's still perception.
There are plenty of colourblind people who can't tell lots of those colours apart. Should we figure out a way to make all the colours distinguishable for them - oh wait...
"Perception is reality" is a saying. For those who are colorblind, there are color codes. For many colorblind people it may be impossible to make 6 or 8 distinguishable colors.
But that you and some others continue to ignore my main point. The problem is that there is not enough contrast between the chosen color and the outline. Your suggestion to lighten up blue would work to make the numbers visible on all maps because the color would have enough contrast to its outline. However, by keeping the black outline, you limit yourself to the lighter shades of the color palette. Virtually by definition light blue will appear close to cyan if you do that. Perhaps not indistinguishably close to some. But closer than it has to be if you just used a white outline for dark colors, particularly blue.
